A severe patch of storms that rumbled across the Eastern U.S. — leaving nine people dead and millions without power — also disrupted an Amazon Web Services data center, affecting service for social media sites like Pinterest, Instagram and Netflix, which host their services at Amazon’s data centers.

Netflix and Pinterest had recovered most of their service by this morning. The worst affected appeared to be Instagram — the Facebook-owned social photo-sharing service remained offline for many users as of this morning, and as of 11 am PT, it hadn’t updated users on its status since its initial service failure. Some users reported on Twitter that service had been restored for them, while others said it remained offline.

The outage affected its Elastic Cloud Compute, Relational Database and Elastic Beanstalk services.
